General Description
The MAX5441–MAX5444 are serial-input, voltage-output, 16-bit digital-to-analog converters (DACs) in tiny µMAX® packages, 50% smaller than comparable DACs in 8-pin SOs. They operate from low +3V (MAX5443/MAX5444) or +5V (MAX5441/MAX5442) single supplies. They provide 16-bit performance (±2LSB INL and ±1LSB DNL) over temperature without any adjustments. Unbuffered DAC outputs result in a low supply current of 120µA and a low offset error of 2LSB.

Features
♦ Ultra-Small 3mm x 5mm 8-Pin µMAX Package
♦ Low 120µA Supply Current
♦ Fast 1µs Settling Time
♦ 25MHz SPI/QSPI/MICROWIRE-Compatible Serial Interface
♦ VREF Range Extends to VDD
♦ +5V (MAX5441/MAX5442) or +3V (MAX5443/MAX5444) Single-Supply Operation
♦ Full 16-Bit Performance Without Adjustments
♦ Unbuffered Voltage Output Directly Drives 60kΩ Loads
♦ Power-On Reset Circuit Clears DAC Output to Code 0 (MAX5441/MAX5443) or Code 32768 (MAX5442/MAX5444)
♦ Schmitt-Trigger Inputs for Direct Optocoupler Interface
♦ Asynchronous CLR
